Hi,
I have downloaded and installed on my pine64+ the distro OMV_3_0_71_Pine64_3.10.105 based on Armbian_5.27_Pine64_Debian_jessie_default_3.10.105 .
After an update from OMV 3.0.71 to OMV 3.0.78 at the reboot the console shows "no interface available" so OMV hasn't an ip adress for the web ui. So i'm stuck in the consolle that is asking username and password.
The problem is that I don't know the username and the password for Debian_jessie and without logging in debian jessie as root I can't fix the problem with my ethernet ... could you help me ?
thanks

Rock64 usb2.0 Power Control Floating GPIO Tutorial Files & Notes |

Greetings,
The purpose of this post is to document the rock64_usb_power_service.sh script , provide instructions and notes for its correct use (tutorial) , and document the installation of the script as a systemd automated service.
The problem that we are solving is that the usb2.0 power regulators are controlled by a hardware line (EN) (gpio2) which is in a floating state when the Rock64 boots. This often results in the usb2.0 ports losing power ( at least momentarily ).
The solution to this problem is to create an executable script , as well an automated service (systemd) , that will export the gpio2 line to user space ( setting it low & turning ON the power regulators ) while also allowing the system admin (user) to control the gpio2 for power cycling devices plugged into the usb2.0 port. This approach to fixing this problem is a win-win in that the usb2.0 power remains on permanently after boot-up for those who want it, and it also allows advanced users the flexibility of being able to power cycle their usb2.0 ports as designed by the Rock64 engineers ( very handy in many use cases ).
The user has complete freedom and control because the script may be run manually (as root) or it may be installed as an automated systemd service. The following tutorial will provide the codes first , then I will discuss how to use them , and finally how to install the usb_gpio_on.service in systemd. After each code section I will give instructions for 1) where to place the script, 2) what permissions to give it, 3) what ownership to give it, and finally how to run it.
The Scripts
Before beginning switch into root operating mode ( and permissions ) with sudo -i (important).
rock64_usb_power_service.sh
Code: #!/bin/bash
# rock64_usb_power_service.sh
#
# Mark H. Harris
# v0.1b
#
#
PWRON=0
PWROFF=1
GP=2
GPOUT="out"
GPPATH="/sys/class/gpio"
GPVALUE="value"
GPMODE="direction"
## remove gpio if already exported
if [ -d $GPPATH/gpio$GP ]
then
echo $GP > $GPPATH/unexport
sleep 2
fi
# export the gpio, and set if ready
echo $GP > $GPPATH/export
sleep 2
if [ -e $GPPATH/gpio$GP/$GPMODE ]
then
echo $GPOUT > $GPPATH/gpio$GP/$GPMODE
sleep 2
echo $PWRON > $GPPATH/gpio$GP/$GPVALUE
fi
The rock64_usb_power_service.sh is the executable script. Place this script in /usr/local/sbin/
Check the spelling very carefully; or things will not work when it comes time to automate the service.
set the ownership, group, and permissions:
cd /usr/local/sbin/
chown root rock64_usb_power_service.sh
chgrp root rock64_usb_power_service.sh
chmod 0754 rock64_usb_power_service.sh
To run the script manually :
sudo -i
/usr/local/sbin/rock64_usb_power_service.sh
To power cycle the usb2.0 port's 5v :
sudo -i
echo 1 > /sys/class/gpio/gpio2/value
echo 0 > /sys/class/gpio/gpio2/value
The above script exports the (EN) gpio2 mux line to user space using the sysfs method, sets the direction "out", and sets the value 0 ( pulling the line low turns ON the usb2.0 power regulators ).
usb_gpio_on.service
Code: [Unit]
Description=set the gpio2 EN line low for usb2.0 power regulator ON
[Service]
ExecStart=/usr/local/sbin/rock64_usb_power_service.sh
Type=oneshot
[Install]
WantedBy=default.target
The above usb_gpio_on.service script is called a systemd "service unit file". This file describes the service to systemd so that systemd knows how to find the executable, and further knows that the service executable only needs to be run once. Again, it is very critical that all the spelling is precise; miss spellings will result is chaos; and of course no fix.
Place this file usb_gpio_on.service in directory /etc/systemd/system/
Set the ownership, group, and permissions for this file :
cd /etc/systemd/system/
chown root usb_gpio_on.service
chgrp root usb_gpio_on.service
chmod 0664 usb_gpio_on.service
Inform systemd that a change has been made to the unit files on disk (very critical)
systemctl daemon-reload
systemctl enable usb_gpio_on.service
Congratulations! At this point the service has successfully run; the gpio2 has been exported, and the gpio2 pin has been pulled low turning on the usb2.0 power regulators.
We are now done; all that is left to do is to reboot your Rock64 !
You can check that this worked after reboot by looking in /sys/class/gpio/ for an export directory called gpio2!
At this point you may go about life on your Rock64 normally -- the usb2.0 power should not drop because the EN line is no longer floating; however, if you like you still have the option to power cycle the usb2.0 ports using the method I detailed above.
Caveat Emptor
If you want to try this tutorial follow two simple rules , or do so at your own risk. Either wait for me to post on the forum that this has been tested multiple times and is 1) safe, and 2) works; or become a beta tester ( a guinea pig ). That means that you contact me on irc and tell me you're testing and that you will be gracious to provide feedback ( including loss of time and|or hair ) so that I know who is using it so far, and whether I need to fix anything or make anything clearer.
Every effort has been made to ensure that this is accurate and free from defects; but we all know the best laid plans of mice and of programmers.
We may at some future point fix this in the dts|dtb file and place in a future image; the problem with that is that users who wish to have the advanced ability to power cycle the usb ports as designed would have to hack the dts first! So we're going to try this and see how it goes.
This method and the script which have been provided have been tested according to this tutorial on my Rock64 production test board, and everything works on my board as described in this tutorial; again, if I need to make anything more clear, or if something is broken ( I certainly hope not ) please let me know asap , preferably on irc.
Thanks much !

We plan to use the Rock64 to create a video conference device on linux, so we need to enable RK3328 h264 encode/decode hardware acceleration.
I have tested the h264 decoding, it is ok. But for h264 encoding, it is not work. The output h264 data of mpp / mpi_enc_test program are all zero.
Has anybody tried the h264 encoding in Rock64?
Thanks

Greetings,
The purpose of this post is to make the Pine Installer script available (on the forum) for Pinebook users who want to create SD cards on their Pinebook using the SD card slot, which will allow making SD cards directly on the Pinebook from the network; this script is similar to the pin64_install_to_emm.sh , as well the rock64_install_to_SD.sh.
The script does require the curl package, as well the jq package.
( This script allows you to burn Pinebook images from the network, to the SD card while booted from eMMC )

Place the script in the normal place /usr/local/sbin/pinebook_install_to_SD.sh
make the script executable with :
sudo chmod 0775 /usr/local/sbin/pinebook_install_to_SD.sh
sudo chown root /usr/local/sbin/pinebook_install_to_SD.sh
sudo chgrp root /usr/local/sbin/pinebook_install_to_SD.sh
To run the script and get usage:
sudo /usr/local/sbin/pinebook_install_to_SD.sh
To run the script and load xenial-i3 :
sudo /usr/local/sbin/pinebook_install_to_SD.sh xenial-i3
If you do not specify a version then the script will pull the most recent (non pre release) from the repos.
( This script allows you to burn Pinebook images from the network, to the SD card while booted from eMMC )

| Pinebook not booting for the 1st time |

I am experiencing very unfortunate event - pinebook that came to me does not boot. I hope the community can help me with this.
Here is my case:
After delivery I tried to start pinebook by hitting the power button. The green power led turned on and nothing happened - screen did not react, no flash, no out of battery sign as many other users had experienced. I powered it down (pressing power button for ~5 seconds), the green power light went off. Then I plugged the charger in and the green power led button turned on again and that's it, nothing else happened. Unplugging the cable does nothing. The plastic around the charger port does not get warmer but the camera does get warmer when the device is plugged in. I tried unplugging the power cord and closing the lid, as I could see the green led light is still on, does not react to the lid.
I let it charge overnight, tried plugging charging cable many times and it made no effect. No other led lights turned on so far.
I wrote a support ticket but still got no response (after 4 days 17 hours passed at the time of the writing of this post).
Does anyone know what can be done in this case? I will gladly do any debugging that could help.
Also, I am not sure if I can unscrew the screws and look into the insides of the laptop without voiding the 30-day warranty in case the device is defective/dead. Can I do that safely? I have a suspicion that it is that the display is not working (just an assumption as of now) so I want to see if it is all plugged correctly inside.
I would also appreciate any other information that can be useful in my case.
Thank you.

| Pinebook Solar charging |

Hello, I am pretty new here.
I got my Pinebook a few weeks ago and everything seems fine except a few flaws which are not as important to me for now.
Whats actually a great thing about the Pinebook is its battery-life...
I highly recommend buying the USB-to-Power Cord along with your Pinebook.
Now to my experiment. I challenged the Pinebook to LIVE WITHOUT A POWER OUTLET FOR TWO WEEKS.
And it went very well with my setup which is pretty low-end.
- Pinebook with USB powercord
- 700mWh Powermonkey Powerbar
- and a Solar Panel from Solarmonkey which has the same size as two large smartphones
So i tried working*/browsing with my Pinebook all (sunny) day while i let the powerbank charge, and if i needed power is would just plug it into the powerbank.
(If you plug it directly into the Solar panel it will only "slowly discharge")
If the weather really was bad (cloudy weather works) you could still work practically 24/7 for one day.
If you have a good weather condition and load the powerbank to full charge, you can work almost 2 days without sun.
The Pinebook is pretty happy with 4.3V for charging it seems.
*Sys- and Network-admin Stuff; Light Programming
tl;dr
So if you actually want to live off the grid for a few days or just wondered if you should buy a powerbank and/or a solar-panel for your Pinebook (and other Devices).
YES TOTTALLY DO IT, it works great. if you have a better/larger Solar Panel you could probably charge this thing.

Hi All,
Just received my Pinebook 14" on Friday. Flat battery when it arrived, but after charging for an hour or so, it did power up.
I liked what I saw, however now I am now having an issue where it will not power on. Here is what I put in the ticket I posted (#1561)...
On Saturday I had some difficulty getting it to power on, but eventually it did. Today (Sunday), it will not power on. When I plug the cord in the red power light by the socket comes on, and the green power light on the keyboard lights, it then displays the battery charging symbol and shows that the battery is fully charged. Then the power light on the keyboard goes out. And I cannot get it to come back on. I have tried pressing the power button in multiple ways, and nothing happens. I have tried the sleep button (Fn-F1) and nothing happens.
Anyone else have this problem?
Also, I opened the ticket on Sunday and have as yet had no response? Anyone else know about how long it takes for them to respond?
Thank you for any help!
